Unlock all the Things achievement not credited

I purchased the last of the felts, decks, and chips that I needed while Steam was undergoing maintenance earlier, and I do not have credit for the Unlock all the Things achievement. I have every achievement except that one and We are the 1%, so there is no reason why I shouldn't be credited with that achievement.

Due to the Steam architecture, achievements cannot be acquired while playing in offline mode or without an active internet connection. For more information on Steam’s policy regarding achievements, please see the following thread:
